I've been using this yoga ball for about a month and it has been very helpful for staying in shape. Especially for wall squats, hip rolls, and back stretches. I find it very fun to work out with and so I've been motivated to excercise. Rated four stars because the colour is quite ugly...I thought it would be a metallic hunter green but it's a dull camo green. I don't like looking at it but it's doing good things for my health so I would recommend it.
